into filenames, such as xxx_classname.php, classname_xxx.php, and classname.php, and so on.
This example attempts to load the MyClass1 and MyClass2 classes from the myclass1.php and myclass2.php files, respectively

Object-oriented design principles are at the heart of oops programming, but most of the Java programmers I've seen are enthusiastic about design patterns like Singleton (singleton), Decorator (adorner), OBSERVER (Observer), Instead of focusing enough attention on learning

Combination
N(Object) is a combinationCombinationTo obtain the reuse method of new functions.
NDelegates a feature to a combined object to obtain the new feature.

Combination
1. (object) combination is a method of reusing new functions by creating an object that combines other objects.
2. delegate the function to a combined object to obtain the new function.
3. Sometimes it is called "aggregation" or "inment", although some authors give special meanings to these terms

In this new series of articles, you will learn how to best design and optimize the Enterprise JavaBeans component, how to reduce RMI communication and JNDI access, and how to use Enterprise applications most effectively. In each article, Brett McLaughlin, the main authority in Enterprise Java programming, will provide best practices or design patterns. Many techn
various components in the program. In order to achieve this goal, the object-oriented design requires that the program be divided into blocks. The size of each block should be smaller than the management level, and then each block is hidden behind the interface, allow them to communicate with each other only through interfaces. For example, if you use an
